Polycarbonate Plastic Injection Molding
Polycarbonate (PC) is known for its combination of clarity and strength. It withstands repeated impacts while maintaining transparency, making it a leading choice for protective covers and optical parts.
Key Properties
- Extremely high impact resistance
- Excellent transparency (up to 90% light transmission)
- Heat resistance up to ~120°C
- Stable dimensions and good dielectric properties
Common Applications
Used in lighting components, safety shields, faceplates, and medical housings. Opaque blends also perform well in electronics and appliance applications.
Design Considerations
Maintain consistent wall thickness (2–3 mm). Use gates positioned away from cosmetic surfaces. For clear parts, polish the mold and manage cooling to reduce internal stress.
Additives and Variants
- UV-stabilized and flame-retardant grades
- PC/ABS blends for better flow and lower cost
- Tinted or opaque versions for aesthetics
When to Choose Polycarbonate
Choose PC when you need clarity and toughness in the same part.
